And it seems like just the ticket to speed-binge through a season of "24" in just 18 hours.
But the approach is more controversial when it comes to videos that people consider art. Netflix has developed a reputation for challenging the norms of entertainment, often in ways that offend more tradition-bound viewers.
The company has offended cinephiles by pushing for movies to be released at home at the same time they appear in theaters and allowing viewers to skip opening credits.
Director Judd Apatow objected to the 1.5x move on Monday, telling Netflix he would call "every director and show creator on Earth to fight you on this."
"We give you nice things," he said on Twitter. "Leave them as they were intended to be seen."
Apatow's works include "The 40 Year-Old Virgin" and "Knocked Up".
A Netflix Australia-New Zealand spokesperson said, "We're always experimenting with new ways to help members use Netflix. This test makes it possible to vary the speed at which people watch shows on their mobiles. As with any test, it may not become a permanent feature on Netflix."
